On a day where a lot of NFL rosters are going to shift, the Detroit Lions made some extra cap room for the 2014 season by restructuring safety Glover Quin's contract, per a source.

Quin, who is signed with the Lions through 2017, was scheduled to make $4.55 million against the salary cap this season, so this move will take some of his base salary of $3.5 million and move it to a signing bonus to create more cap room now, while meaning less cap room in future years.

How much of his salary was moved was not disclosed. The restructure has not affected how much money Quin will make or how many years he is under contract.

This is a common move by teams looking to open up some salary-cap space.
